Abstract: Abstract of the Disclosure The present invention relates to a magnetic fuel purifier equipped to have a double purifying effect on liquid fuel and the like, equipped with a centre shaft around which rotates an inner pre-purifier and an outer purifier.  In the outer purifier the fuel passes through a specially sintered bronze ball filter. The center shaft is equipped at its bottom with a rigidly applied surrounding magnet to pick magnetic particles from out of the fuel.  The case for the fuel purifier is made from a transparent non-magnetic material which is as clear as glass to make it easier to check when the purifier is filled with contaminants and to determine when the case needs to be emptied and cleaned.

Abstract: Abstract of the Disclosure In the present invention a single shaping mold conforming to the outline and contour of the bent glass sheet is employed, onto which a heat-softened glass sheet is dropped to impart the bending force to the glass.  Immediately after each glass sheet leaves a heating furnace, it is elevated by means of a flat vacuum platen which is brought into contact with the upper side of the glass sheet.  When the vacuum platen and the glass sheet are raised to an elevated position, the shaping mold is conveyed into a position beneath the glass sheet, the vacuum is released, and the glass sheet drops onto the shaping mold to effect the bending.  The shaping mold is then retracted from beneath the vacuum platen ant passed into a tempering station where blasts of air are directed onto the opposite surfaces of the glass sheet to temper the glass.  This arrange-ment greatly simplifies change-over from one shape to another since the single bending mold is the only major element which muse be reconstructed. Another important feature of the present invention is that the arrangement may be readily adapted to bending and tempering a plurality of glass sheets simultaneously, thereby greatly increasing the productivity of the instal-lation..

Abstract: REINFORCED SHOCK RESISTANT RESIN     STRUCTURE AND ITS RELATIVE METHOD OF MANUFACTURE          Abstract of the Disclosure The resin structure according to this invention is used to produce tanks, helmets or the like.  The false work consists of elementary pockets B with tricot weave to obtain a polygonal reticulate fabric.  The tricot weave pockets B are manufactured commencing from a central focal point and proceeding spiralwise progressively increasing the number of stitches up to a pre-determined value.  The weaving process is continued until the desired length of the pocket is reached.  While a pre-determined tension is given to pockets B, these are overlapped and introduced on the male part of a die, the whole is then introduced in the complementary cavity of the die where liquid resin is poured.  The resin incorporating the textile structure is then pressed so as to obtain the desired shape.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention provides light and heat controlling panels which may be used for example as facings for walls or as roof elements.  The panels can also be used as energy concentrators for concentrating light energy onto energy collectors associated with the panels or with the walls, etc. on which they are located.  Thus, the panels can be used as an equipment for the automatic control of the incidence of solar radiation.  Each panel consists of two spaced light-transmitting wall elements between which are disposed a plurality of light-impervious elements horizontally-oriented and parallel to each other, the upper and lower-sides of two immediately adjacent elements being of different profile and forming an incidence and a concentration space for the radiation.  An energy collector may be disposed in this concentration space.  Depending on the angle of incidence of the solar radiation a certain amount is reflected back through the incoming side into the outer space, the amount of reflected and transmitted energy varying with the change of seasons. Energy transmission through the panel will be increased in the cooler seasons characterised by lower angles of incidence, while the energy reflection is increased in the hotter seasons characterised by higher angles of incidence.  The relative energy transmission and reflection is controlled by means of choice of the shape and disposition of the element profiles.  Heat control of a building is achieved by using the panels as a curtain wall therefor.
